Abstract (en)
A display device includes: a plurality of pixel blocks each including a plurality of pixels; a scan driver supplying a scan signal to the scan lines and to supply a control signal to the control lines; a data driver supplying an image data voltage or a low grayscale data voltage to the data lines; and a power supply supplying a reference voltage to the pixels, wherein the pixels are configured to receive the image data voltage during a first scan period of a frame, and to receive the low grayscale data voltage during a second scan period of the frame, and the reference voltage supplied to a first pixel row of at least one of the pixel blocks in the first scan period is different from the reference voltage supplied to a last pixel row of at least one of the pixel blocks in the first scan period.
